Looking to buy an Unused Silktouch with Unbreaking 3 Diamond pick

As the title states, I am looking for an Unused Silktouch with unbreaking 3 Diamond pick I dont care if it has efficiency on it at all but it must have unbreaking 3 and silk on it. I am willing to pay 20k to the first person who wants to sell me one. No questions asked, I dont care if you won it in an auction for 10k.

I am only buying one so first person to sell to me gets the 20k. Anyways happy hunting and xp farming.

P.S. if you haven't already go check out the landscaping contest i am hosting.
